Bloated Keyword Groups or Campaigns
It’s easy to overindulge on the number of keywords you have within a search campaign’s ad group. Sure, you will want to have your ads show for all the keywords relevant to your landing page, but you can go too far in this respect.
Having more keywords than clicks is a bad sign
With a huge number of keywords, you are bound to have many automatically fall under the “low search volume” category. Google AdWords states that low search volume keywords “will be inactive until its search traffic increases” which means that super-niche keywords are a waste of time, essentially deadweight stuffed within an ad group.
Some niche keywords will occasionally get clicks, but if there aren’t enough clicks overall, then the results around that keyword aren’t statistically significant and it’s a shot in the dark as to what bid to set. These niche keywords also deflect clicks from phrase and broad match keywords, which means that they have less historic data to base bids on.
Any search queries that have enough data behind them can be separated out into their own exact and broad match keyword, or even better: these stand-out keywords can form a new ad group to improve Quality Scores with a closely matching ad and/or landing page.
